Pull Request Overview

This PR refactors the free-form component architecture to introduce a centralized store pattern using createInjectionState from VueUse. The main purpose is to replace the previous dependency injection system with a more structured store approach for managing form state, schema helpers, and configuration.

Key changes include:

• Introduction of a new FreeFormStore using createInjectionState pattern
• Removal of multiple individual injection keys in favor of centralized store access
• Addition of field change tracking with metadata for better form state management
